4. Configuring the PPP Dial-Out Connection

There are two basic modes of operation of the ppp driver: "Interactive" and "Automatic".

In Interactive mode you:

• Manually establish a connection to your ISP,
• Browse, surf, transfer files and mail, etc...,
• Manually disconnect from your ISP.

In Automatic mode, the PPP program silently watches what goes on inside the FreeBSD system and automagically connects and disconnects with your ISP as required to make the Internet a seamless element of your network.

In this section we'll address the configuration(s) for both modes with emphasis on configuring your `ppp` environment to operate in "Automatic" mode.

4.1. Backing up the original PPP configuration files

4.2. Create your own PPP configuration files

4.2.1. The '/etc/ppp/ppp.conf' file

4.2.2. The '/etc/ppp/ppp.linkup' file

4.3. IP Aliasing
